This mini vanilla cake is a tender, buttery two-layer cake baked in 6-inch pans and finished with tangy vanilla cream cheese frosting. Its soft crumb and classic flavor make it just right for birthdays, celebrations, or a smaller gathering.
Preheat the oven to 350°F (175°C). Spray two 6-inch cake pans with baking spray, line the bottoms with parchment rounds, and spray the parchment.
Sift the flour into a medium bowl. Add the baking powder, baking soda, and salt, whisk to combine, and set aside.
With a mixer, beat the butter, oil, and sugar on high speed for about 3 minutes, until pale and fluffy. Add the sour cream and vanilla and mix on medium until combined, scraping down the bowl.
Add the eggs one at a time, mixing on medium-high after each addition. Beat for about 1 minute, then scrape the bowl.
With the mixer on low, add one-third of the dry ingredients, followed by half the buttermilk. Repeat with another third of the dry ingredients and the remaining buttermilk, then mix in the remaining dry ingredients just until combined.
Divide the batter evenly between the prepared cake pans and smooth the tops.
Bake for 25–30 minutes, until a toothpick inserted in the center comes out clean. Let the cakes rest in their pans for 10 minutes, then turn them out onto a wire rack and cool completely.
Beat the cream cheese and slightly cold butter on high speed for about 3 minutes, scraping the bowl as needed. Gradually mix in the sifted powdered sugar. Add the vanilla, salt, and heavy cream; mix on low until combined, then beat on high for 1–2 minutes until fluffy.
Use a serrated knife to trim the domed tops from the cooled cakes. Place a small dab of frosting on the serving board to secure the first layer. Spread about 3/4 cup frosting over it, then add the second cake layer. For a flat top, position the second layer with its bottom facing up.
Spread a thin crumb coat over the cake and freeze for 15 minutes to set it. Cover the cake with the remaining frosting, pipe on any extra decoration, and finish with sprinkles if desired.
